A project consists of three tasks: A, B, and C. Task A is known to take five days for sure. Tasks B and C are each dependent on A. B takes five days. C takes seven days with a probability of 0.5 and three days with a probability of 0.5. What is the expected completion time of the project

Answer:

Well -7>-7.5

Step-by-step explanation:

Negative numbers are that the Humber that is closest to 0 is the greatest. Like in -7 and -7.5, the -7 is closer to 0 so its greater.

Answer:

the answer to your question is -7.5<-7

Using Venn probabilities, there is a 0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

For this problem, the events are given as follows:

From the text, the probabilities are given as follows:

Hence the "or probability" is given by:

[tex]P(A \cup B) = \frac{10}{40} + \frac{15}{40} - \frac{4}{40} = \frac{21}{40} = 0.525[/tex]

0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

The scores in order from the greatest to the least is 4, 3, 1, 0, -1, -2, -3.

The inequality that shows the relationship between the greatest and least number is 4 > -3.

On the number line, four is greater than -3.

Integers are whole numbers. It is a number without a fraction or decimal component. Integers can either be positive, negative or zero. Examples from integers are 0, -1 and 1.

The farther a positive number is from zero on the number line, the greater the positive number. The closer a negative number is to zero on the number line, the greater the negative number.

For example, 10 is greater than 4 because 4 is closer to 0 when compared to 10. -4 is greater than -10 because -4 is closer to 0 than -10 on the number line.

Here are inequality signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

The sign that would be used to show the relationship between the greatest and the least number is the greater than sign (>)

Step-by-step explanation:

Answer:

The triangles formed are iscocleles triangles making their bases the same angle measures. Additionally, RST anf RGT are congruent since they are each equal to 1/2 of RQTS

We also know that the interior angles of any triangle add up to 180°

Therefore,

m<R + m<T + 126 = 180

m<R + m<T = 54

Since m<R and m<T are equal, R and T must be equal to 27

m<R=27

m<t=27

Therefore,

m<1=27

m<2=27

m<3=27

m<4=27

m<5=126

Step-by-step explanation:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h. i hoped this helped sorry if it didnt

Answer:

$4,750.

Step-by-step explanation:

To determine the rental value of the apartment in the tenth year, knowing that it is worth 1,600 during the first year but that it will be adjusted annually to 11.5%, the following calculation must be made:

X = 1,600 x (1 + 0.115) ^ 10

X = 4,751.91

Thus, at ten years, rounded to the nearest tenth, the rental value will be $ 4,750.

The rent of the apartment during the 10th year of living in the apartment is 4,751.9.

Let x represent the rent  of the apartment

Hence:

x= 1,600(1 + 0.115)^10

x=1,600(1.115)^10

x=4,751.9

Inconclusion the rent of the apartment during the 10th year of living in the apartment is 4,751.9.

Answer:

  (xy+5)/(xy+3)

Step-by-step explanation:

Given a ratio of rational expressions, you want the simplified version.

The colon separating the two expressions is one of the ways a ratio is written. In this context, it can be replaced by "divided by" (÷). Of course, the division is carried out in the usual way: multiplying by the inverse of the denominator.

The product is simplified by cancelling common factors. This requires each of the polynomials be factored.

  [tex]\dfrac{x^2y^2-4}{x^2y^2+xy-2}\div\dfrac{x^2y^2+xy-6}{x^2y^2+4xy-5}=\dfrac{x^2y^2-4}{x^2y^2+xy-2}\times\dfrac{x^2y^2+4xy-5}{x^2y^2+xy-6}\\\\=\dfrac{(x^2y^2-4)(x^2y^2+4xy-5)}{(x^2y^2+xy-2)(x^2y^2+xy-6)}=\dfrac{(xy-2)(xy+2)(xy-1)(xy+5)}{(xy-1)(xy+2)(xy-2)(xy+3)}\\\\=\boxed{\dfrac{xy+5}{xy+3}}[/tex]
